Product Description
Cat
IMP-6461
Official Symbol
KAT2A
Product Overview
The peptide corresponding to amino acids 726 - 837 that contains the bromodomain sequences of KAT2A (GCN5) (accession number NM_021078.2) was expressed in E. coli and contains an N-terminal His-Tag and C-terminal FLAG-Tag with an observed molecular weight of 19.4 kDa. It shows binding specificity for acetylated H2AK5, H3K9, H3K14, H3K9/K14, H4K8/K16, H4K16 and H4K5/8/12/16.
Description
GCN5, also known as K (lysine) acetyltransferase 2A (KAT2A), is a component of the ATAC complex, which is a complex that specifically exerts histone acetyltransferase (HAT) activity on histones H3 and H4. KAT2A (GCN5) acts as a histone acetyltransferase to promote transcriptional activation. In the case of HIV-1 infection, it is recruited by the viral protein TAT and regulates TAT's transactivating activity. In addition, evidence suggests KAT2A (GCN5) may play a role in the induction of chromatin remodeling of proviral genes. KAT2A (GCN5) also functions as a repressor of NFkB by promoting ubiquitination of the NFkB subunit RelA in a HAT-independent manner. KAT2A (GCN5) contains a bromodomain that recognizes acetylated histone lysine residues and functions as a 'reader' of these epigenetic histone marks to regulate chromatin structure and gene expression by linking associated proteins to the recognized acetylated nucleosomal targets.
